Bug#902658: apache2: apachectl graceful/restart results in segfault
I have the same problem with the same Debian and Apache2 version
(upgrade testing/buster 2018/07/07):
/var/log/kern.log:
Jul 9 18:25:28 eussa kernel: [12436.633037] /usr/sbin/apach[12386]: segfault at 7f5c82d98660 ip 00007f5c82d98660 sp 00007ffcfaf711f8 error 14 in libcap-ng.so.0.0.0[7f5c82d70000+200000]
Jul 9 18:25:28 eussa kernel: [12436.708687] /usr/sbin/apach[12387]: segfault at 7f5c82d98660 ip 00007f5c82d98660 sp 00007ffcfaf72628 error 14 in libcap-ng.so.0.0.0[7f5c82d70000+200000]
But for me, the culprit was "nscd", if i start or restart apache2 with
service "nscd" started, i have a segfault.
If i stop "nscd", apache2 start normaly and after i can start
"nscd". But after a new "apache2 restart" produce a segfault.
